DBusObjectManagerServer

`GDBusObjectManagerServer` is used to export `GDBusObject` instances using the standardized `org.freedesktop.DBus.ObjectManager` interface. For example, remote D-Bus clients can get all objects and properties in a single call. Additionally, any change in the object hierarchy is broadcast using signals. This means that D-Bus clients can keep caches up to date by only listening to D-Bus signals.

since: 2.30

DBusObjectProxy | A `GDBusObjectProxy` is an object used to represent a remote object with one or more D-Bus interfaces. Normally, you don’t instantiate a `GDBusObjectProxy` yourself — typically `GDBusObjectManagerClient` is used to obtain it. since: 2.30

Use `g_resolver_lookup_by_address()` or `g_resolver_lookup_by_address_async()` to look up the hostname for a `GInetAddress`.
InetAddressMask | `GInetAddressMask` represents a range of IPv4 or IPv6 addresses described by a base address and a length indicating how many bits of the base address are relevant for matching purposes. These are often given in string form. For example, `10.0.0.0/8`, or `fe80::/10`. since: 2.32
InetSocketAddress | An IPv4 or IPv6 socket address. That is, the combination of a `GInetAddress` and a port number.
InputStream | `GInputStream` is a base class for implementing streaming input.
IOModule | Provides an interface and default functions for loading and unloading modules. This is used internally to make GIO extensible, but can also be used by others to implement module loading.
IOStream | `GIOStream` represents an object that has both read and write streams. Generally the two streams act as separate input and output streams, but they share some common resources and state. For instance, for seekable streams, both streams may use the same position. since: 2.22
ListStore | `GListStore` is a simple implementation of `GListModel` that stores all items in memory.
MemoryInputStream | `GMemoryInputStream` is a class for using arbitrary memory chunks as input for GIO streaming input operations.

MenuModel

`GMenuModel` represents the contents of a menu — an ordered list of menu items. The items are associated with actions, which can be activated through them. Items can be grouped in sections, and may have submenus associated with them. Both items and sections usually have some representation data, such as labels or icons. The type of the associated action (ie whether it is stateful, and what kind of state it has) can influence the representation of the item.

since: 2.32

Settings | The `GSettings` class provides a convenient API for storing and retrieving application settings.
SettingsBackend | The `GSettingsBackend` interface defines a generic interface for non-strictly-typed data that is stored in a hierarchy. To implement an alternative storage backend for `GSettings`, you need to implement the `GSettingsBackend` interface and then make it implement the extension point `G_SETTINGS_BACKEND_EXTENSION_POINT_NAME`.

TcpConnection | This is the subclass of `GSocketConnection` that is created for TCP/IP sockets. since: 2.22
TcpWrapperConnection | A `GTcpWrapperConnection` can be used to wrap a `GIOStream` that is based on a `GSocket`, but which is not actually a `GSocketConnection`. This is used by `GSocketClient` so that it can always return a `GSocketConnection`, even when the connection it has actually created is not directly a `GSocketConnection`. since: 2.28

PollableOutputStream | `GPollableOutputStream` is implemented by `GOutputStream`s that can be polled for readiness to write. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style. since: 2.28

Seekable | `GSeekable` is implemented by streams (implementations of `GInputStream` or `GOutputStream`) that support seeking.
SocketConnectable | Objects that describe one or more potential socket endpoints implement `GSocketConnectable`. Callers can then use `g_socket_connectable_enumerate()` to get a `GSocketAddressEnumerator` to try out each socket address in turn until one succeeds, as shown in the sample code below.

TlsProtocolVersion

The TLS or DTLS protocol version used by a `GTlsConnection` or `GDtlsConnection`. The integer values of these versions are sequential to ensure newer known protocol versions compare greater than older known versions. Any known DTLS protocol version will compare greater than any SSL or TLS protocol version. The protocol version may be `G_TLS_PROTOCOL_VERSION_UNKNOWN` if the TLS backend supports a newer protocol version that GLib does not yet know about. This means that it’s possible for an unknown DTLS protocol version to compare less than the TLS protocol versions.
